If sand has a specific-heat capacity of 835 JkgC how much energy must be added to a 2kg pile of it to increase its temperature from 40C to 50C Show your work?

To calculate the energy required to increase the temperature of the sand, you can use the specific heat capacity formula: Energy = mass x specific heat capacity x change in temperature. Plugging in the values: Energy = 2kg x 835 J/kg°C x (50°C - 40°C) = 16700 Joules. Therefore, 16700 Joules of energy must be added to the 2kg pile of sand to increase its temperature from 40°C to 50°C.
